Using the Shield With Arduino UnoThe shield is fulli compatible with Arduino Uno. Just download the test code and run it.

Using the Shield With Arduino Mega 2560The Mega 2560 uses different pins for the SPI then the Uno.In order to make it work connect the pins using some wire. MOSI - pin 51 connect to pin 11 MISO - pin 50 connect to pin 12 CLK - pin 52 connect to pin 13 CS - pin 53 connect to pin 10

Then download the code for Mega 2560 from the bottom the page.
